Prompt Actions
In VNgen terminology, prompts are animated icons which sit on top of the textbox and display different sprites to indicate to the user whether the text typewriter effect is in-progress, waiting for user input, or in auto mode. Although using prompts is entirely optional, taking advantage of them is a simple and effective way to add visual flair and, more importantly, visual feedback to your UI.
Prompts support the full range of actions available to other entities, and can even be customized for each character on-screen, taking them far above and beyond being just a simple decoration.
In this section we'll examine available prompt actions covering five basic operations: create, modify, replace, destroy, and animate.
